Name: Gamble-Skogmo, Inc.; Minneapolis (MN); Coronado Mfg.Co.    (USA)  
Brand:
Coronado
Abbreviation: gamble-sko
Products: Model types
Summary:

Gamble-Skogmo, Inc.; 700 Washington Ave. N., Minneapolis, Minnesota. Also Coronado Mfg.Co.; St. Paul, Minnesota and Los Angeles, CA.

Unfortunately the name Coronado was used by different manufacturers as trade name and/or company name.

(Brand: Coronado - but see also Coronado Mfg.Co. or Montgomery Ward - Model name "WG" indicates that it is manufactured by Wells-Gardner for Montgomery Ward Airline radios. "BR" stands for Belmont Radio as manufacturer etc.). Gamble Stores, Inc. is either a sister or a daughter company (we believe). Riders Index 1 indicates that also Western Auto Supply of California sold "Coronado". Radios have appeared in Rider manuals with a date as early as April 1935 but production may have been started a few years earlier. From 1948 at least for radios with number ??RA-43-.... the two first digits in reverse order tell the first production season (mostly second year) - until about 1953 (35).

Founded: 1925
Closed: 1982
Production: 1935 -
History:
Reference: University of Minnesota School of Social Work web site. Bertin Gamble and Philip Skogmo were boyhood friends in Arthur, North Dakota (40 miles northwest of Fargo). They were born at the end of the 19th century and grew up together in Arthur. As young men they each came separately to Minnesota and worked in a variety of jobs. In 1920, they pooled their resources, borrowed some money and bought an auto dealership in Fergus Falls, Minnesota. Soon they discovered that the sale of auto parts and accessories was the most profitable part of their car dealership. So, in March 1925, they opened the first Gamble Auto Supply store in St. Cloud. By 1928, they had 55 stores, moved their headquarters to Minneapolis, and were off and running. Eventually, Gamble stores were franchised, and by 1939 there were 1500 Gamble dealers and 300 corporate stores in 24 states.
From the mid 1940s to the end of the 1970s, Gamble and Skogmo diversified their businesses and branched out into many new endeavors, including a discount division, financial services, real estate, and retail businesses such as Aldens mail order company, Womans World Shops, Red Owl Grocery and Snyder Drug stores. At the end of this period of growth, Gamble-Skogmo was the 15th largest retailer in the United States with 4200 outlets and 26,000 employees in 39 states. Following the retirement of Bert Gamble, the company was sold to the Wickes Co. of California. The purchase was highly leveraged, the combined companies struggled, Wickes filed bankruptcy in 1982, and the empire was sold off in pieces.
About the Gamble-Skogmo Fund:
In 1948, Mssrs. Gamble and Skogmo each established family foundations supporting youth, education, health and religious organizations. In 1982, the trustees of the separate foundations voted to merge the two and formed a supporting organization of the Minneapolis Foundation called The B.C. Gamble and P. W. Skogmo Foundation with combined assets of $13,000,000. For 10 years the foundation continued its philanthropy following the spirit of its founders in five focus areas: (1) disadvantaged youth and families; (2) people with disabilities; (3) low-income senior citizens; (4) secondary and higher education; and (5) health care, research and education. As of 1992, the separate foundation became a field of interest fund of the Minneapolis Foundation.
